A lack of rice could be the next big strain on the global food supply. Bloomberg says the challenge may come from a lack of rain in parts of India, which is, by far, the biggest rice exporter in the world. The drier weather has caused Indiaâ€™s rice planting area to contract to its smallest level in three years. The threat to Indiaâ€™s rice production comes when countries across the world are struggling with the soaring cost of food and runaway inflation. The worldâ€™s total planted area for rice has dropped by 13 percent this season because of a lack of rainfall. Traders fear diminished rice production will hurt Indiaâ€™s battle with inflation and trigger export restrictions. Billions of people around the world depend on rice and India accounts for 40 percent of the worldâ€™s rice trade. Indiaâ€™s government has already curbed exports of wheat and sugar to safeguard their food supply.
